We report fetal intracranial hemorrhage in term siblings from consanguineous parents, spontaneously occurring in the third trimester of pregnancy. Prenatal ultrasound in one case and postnatal MRI in both demonstrated massive parenchymal bleeding involving large areas of the cerebral cortex, white and gray matter. Vasculopathies, vascular malformations, coagulopathies, thrombocytopenia and relevant metabolic disorders could be excluded.

Background: Diprosopus is one of the rarest anomalies. It typically manifests as bilateral alterations and often involves anomalies within the cranial structures. In this report, we present a case of a fetus with diprosopus diagnosed prenatally.

Background: Anatomical variations in the circle of Willis (CoW) arteries are common and can affect hemodynamic stress, thereby influencing the risk of cerebrovascular pathology. Previous studies have suggested sex differences in CoW anatomy, but findings vary due to limited study population size and different measurement methods. This study aims to investigate sex differences in artery diameters, anatomical variants and bifurcation angles of the CoW using a large population cohort and semi-automatic measurements.

Background: Thick fetal corpus callosum (CC) is a rare finding and its significance in isolation is not clear. In this retrospective study, we aim to gain insight into the microarchitecture of CC in a cohort of fetuses with thick and short CC (isolated or associated with mild extra-/intracranial abnormalities) as seen on ultrasound (US), by using prenatal magnetic resonance (MR) diffusion tensor imaging (DTI) with fiber tractography, thereby allowing better characterization for postnatal prognosis.
Methods: Twelve fetuses met the inclusion criteria on US.
Prenatally diagnosed intracranial hemorrhage in the fetus is associated with a wide range of neonatal disorders, from completely uncomplicated physiological development to severe neurological impairment or death. The incidence is 0.6-1/1,000 births.

Premature deliveries and preterm newborns are of a special significance to obstetricians. Despite great improvement in neonatal intensive care in the last two decades, prematurity is still the leading cause of neonatal mortality and morbidity. Complications associated with premature deliveries are malpresentation, prolapse of the umbilical cord, entrapment of some parts of the fetal body, as well as severe bruising or bone fractures.
